"Heather" and Non-Heather Colors are Not the same Fit & Material
Special Size: 27.5" Full Length, Size: Large, Color: Space Dye Slate
I bought these in one of the "heathered" colors and loved how soft they were. They are really comfortable and stretchy, thick enough that they can be worn on their own. They are not a perfect fit, but fit well enough and I can overlook this because of how smooth they feel.
I wanted to try other colors and only realized after purchasing that the non-heathered colors were a different material. I was able to return them but they should probably be listed as a separate item. They have an entirely different fit and texture and I would not recommend.
Five stars for the heather colors, one star for the non-heather version.

Comfy!
Special Size: 27.5" Full Length with Pockets, Size: Large, Color: Black
Super comfy, not as much tummy control as I would like but perfect for house work, going to the gym or grocery shopping. Love that these have pockets!! Thin so not too hot and stretchy too.

Great leggings!
Special Size: 27.5" Full Length with Pockets, Size: Medium, Color: Black
These are great leggings! They’re my third pair. They are comfortable, lightweight, and fit great. I wouldn’t say they are buttery soft as compared to other leggings that are listed the same texture, however they are soft and smooth. The pockets are a must and are positioned perfectly.

So excited I found these!

Extremely impressed with these leggings! These athletic leggings are absolutely amazing! The material is incredibly soft and feels so comfortable against the skin. The quality is top-notch, with a durable yet flexible fabric that moves perfectly with your body. They are completely squat-proof, which makes them perfect for workouts, and they stay in place without sliding down, no matter how much you move. Some of my more expensive name brand leggings don’t check all the boxes; as these do! These leggings truly combine comfort, quality, and performance—highly recommended!
Also- I am 5’3/5’4 and these hit right at my ankle
